LAVA Signature enameled cast-iron cookware is sand-cast, painstakingly finished by hand, and then coated with three layers of very special enamel. Each piece is fired twice in a state-of-the-art furnace to bond the enamel coatings with the cast iron. No other procedure yields cookware that cooks so evenly and conducts and retains heat so well. Only the best cookware in the world is made this way. Lava’s non-reactive enamel surface seals flavour into food and away from the cast iron unlike standard cast iron pans that are factory Pre-Seasoned or require seasoning before use.
